The [[Pharynx - Anatomy & Physiology|pharynx]] is the chamber connecting the [[Oral Cavity Overview - Anatomy & Physiology|oral cavity]], [[Nasal Cavity - Anatomy & Physiology|nasal cavity]], [[Oesophagus - Anatomy & Physiology|oesophagus]] and [[Larynx - Anatomy & Physiology|larynx]]. The [[Pharynx - Anatomy & Physiology|pharynx]] is divided into the [[Nasopharynx - Anatomy & Physiology|nasopharynx]], oropharynx and [[Larynx - Anatomy & Physiology#Laryngeal Pharynx|laryngeal pharynx]] which all have different functions, innervation and develope differently. The oropharynx is the oral section of the [[Pharynx - Anatomy & Physiology|pharynx]].

The oropharynx is innervated by the '''glossopharyngeal nerve''' ([[Cranial Nerves - Anatomy & Physiology|CN IX]]). It is divided by the '''glossopalatine arch''' from the [[Larynx - Anatomy & Physiology#Laryngeal Pharynx|laryngeal pharynx]].

The oropharynx has a '''stratified squamous epithelium'''. The oropharynx is keratinised in ruminants. The '''lamina propria''' contains aggregates of lymphoid tissue (called tonsils) in several parts of the oropharynx.
